How sad is this that CNN makes it a "breaking news" piece on top of their website. Big freaking deal! Get to real news.

A statement from the company said: "While the relay functioned without issue during a number of high-profile events -- including the New Orleans Bowl, the New Orleans Saints-Carolina Panthers game, and the Sugar Bowl -- during Sunday's game, the relay device triggered, signaling a switch to open when it should not have, causing the partial outage.

"This device has since been removed from service and new replacement equipment is being evaluated."

Yeah Entergy's statement does not place blame on anyone. I think all everyone wants to know is who was at fault.

So the blame falls on the company that made the switch, right?
Well, the next natural question is what about the switch gear box failed? Was it a mechanical failure during normal operation (if so, bad manufacturing), did some electrical event cause an issue that eventually showed its self?

I guess since they seem to be saying the the "abnormality" the switch gear detected to activate didn't actually happen, so the switch gear just did it on it's own. Was it a mechanical issue or a "program" issue?

Then, you'd ask yourself, is there an inspection that can be performed to make sure this problem doesn't happen or you can catch it before it does?

relays go bad, it happens but you would think they would have a backup circuit for something as big as the superdome. Generators should kick power on as soon as power is lost and power should never go out... getting power from an UPS system until the generators take over.

The emergency lights did come on immediately. From what I've heard, the problem was fixed within minutes. Most of the "black out" was waiting for the lights to warm back up.

They have backup generators already but that would be one massive UPS system to keep all the electrical on until backup could be switched over. UPS is usually used only for essential equipment.
